- Any evidence of primary angle closure (a narrow angle as defined above, but with PAS and/or IOP > 21 mmHg) or primary angle closure glaucoma (visual field defect or glaucomatous optic neuropathy).
- Previous intraocular surgery or laser treatment, such as cataract surgery, laser trabeculoplasty, trabeculectomy, laser peripheral iridectomy, and laser iridoplasty
- Sign of prior acute attack, such as glaucomatous fleck, keratic precipitates, or iris atrophy.
